Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance.

The table below shows examples of common metamorphic rocks. Its basic component is calcium carbonate. Other examples include quartzite hornfels and novaculite. Marble is a metamorphic rock that is formed from the sedimentary rock limestone.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Marble is commonly used for sculpture and as a building material. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. The extensively known example of non foliated metamorphic rock is a marble.

Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Remember these rocks are formed under extreme heat and pressure. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window.

Non foliated metamorphic rocks do not have a banded or layered appearance. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Its composition is equal to that of granite but forms alternating layers of clear and dark minerals. Anthracite is a type of coal with a high carbon count few impurities and with a high luster meaning it looks shiny.

Examples of metamorphic rocks. Examples of metamorphic rocks include anthracite quartzite marble slate granulite gneiss and schist.
